Abstract (en)

[origin: EP0049755A2] A magnetic head assembly for use in transducing coaction with a flexible rotating magnetic disk, comprises a magnetic head (18) mounted on a pivoted support arm for arcuate movement across the disk. The head has a central transducing gap (32) on a centre rail (38) between symmetrical pairs of grooves (30A, 30B, 34A, 34B) and an offset groove (40) closest to the outboard face (36) of the head. The arrangement provides compensation for skew as the head is moved from the inner to the outer tracks on the disk.
